Emerson KJ4001X1-NB1 Dual Left Cable Extender – 12 VDC, 8A

Description Product Description The Emerson KJ4001X1-NB1 is a Dual Left Cable Extender for DeltaV systems. It extends the LocalBus to additional I/O carriers on the left side. This module supports high-current backplane power up to 8A at 12 VDC. Use it to build larger or more flexible distributed control racks. Technical Data – Sorted by Importance Brand & Model Brand: Emerson Product number: KJ4001X1-NB1 Product type: Dual Left Cable Extender Electrical Specifications LocalBus power: 12 VDC at 8A Designed for Emerson DeltaV LocalBus backplane Temperature Range Ambient operating: -40°C to 70°C Suitable for extreme cold and hot environments Environmental & Mechanical Endurance Shock rating: 10g half sine wave for 11 msec Vibration: 1 mm peak-to-peak (5–16 Hz), then 0.5g (16–150 Hz) Airborne contaminants: meets ISA-S71.04–1985 Class G3 (harsh environment) Relative humidity: 5% to 95% non-condensing Protection rating: IP20 Installation Guide Mount the extender on the left side of your DeltaV carrier. Connect the dual cables to the adjacent LocalBus ports. Ensure total backplane current does not exceed 8A. Keep ambient temperature between -40°C and 70°C. Debugging & Maintenance Ease LED indicators show LocalBus power status. No special tools required for replacement. Inspect cable connectors for dust or corrosion annually. The module operates without firmware updates. Compatibility Works exclusively with Emerson DeltaV LocalBus systems. Compatible with left-side I/O carriers only. Do not use for right-side or redundant bus extensions. Pairs with 3300 XL 11 mm Proximity Probes in same cabinet (separate systems). Certifications Designed to ISA-S71.04–1985 Class G3 for corrosive atmospheres Meets Emerson DeltaV hardware standards Shock and vibration tested per industrial control requirements Packing List 1 x Emerson KJ4001X1-NB1 Dual Left Cable Extender 2 x LocalBus extension cables (attached) No mounting screws included – reuse existing DeltaV hardware. Warranty & Shipping Warranty: 12 months from delivery date. Shipping carriers: FedEx, UPS, DHL with real-time tracking. Typical Applications Expand DeltaV systems to additional left-side I/O carriers. Connect remote LocalBus segments in large control panels. Use in Class G3 environments like chemical plants. Enable hot or cold climate installations (-40°C to 70°C). Diagnostic Capability No onboard diagnostics – rely on DeltaV controller for bus health. Visual inspection confirms physical cable integrity. Measure LocalBus voltage at the far carrier to check drop. FAQ – Frequent Questions & Real Experience Q: Can I use this extender on the right side of the rack? A: No. The KJ4001X1-NB1 is specifically for left-side extension only. Q: What happens if I exceed 8A? A: The LocalBus may brown out. Add another power supply module. Q from user: Will this work with older DeltaV versions? A from engineer: Yes. It works with all DeltaV systems that use LocalBus carriers. Q: Does it support redundant LocalBus? A: No. This extender handles single path only. Use dual extenders for redundancy. Q about storage: How to store for 2 years? A: Keep in dry, ESD-safe bag at -40°C to 70°C. Buying Guide – How to Choose the Right Cable Extender Choose KJ4001X1-NB1 only for left-side DeltaV LocalBus expansion. Verify total current stays below 8A for all connected carriers. Select this model when ambient temperature drops below freezing. For corrosive areas (Class G3), this extender provides proper protection. Order one spare extender for every 10 installed to reduce downtime. Still have a question? For bulk order or installation support: 86 158 8020 0923 (WhatsApp) Copyright © 2026 PLCDCS HUB Limited.
